一般来讲，深色的较浅色花岗石易退色，因深色(如黑色、墨绿色)花岗石的矿物构成主要是辉石、角闪石、基性斜长石、磁铁矿等。浅色花岗石主要为酸性斜长石、钾长石、黑云母、石英等。矿物一般在地下形成，有些矿物先形成，有些后形成。先形成的往往是原子量较重的无素，位置较深，氧的供应较少，压力较大；后形成的则相反。因此不同的矿物一般有不同的形成时期，其次序大致是：深色矿物：橄榄石-辉石-角闪石-黑云母;浅色矿物：基性斜长石-酸性斜长石-钾长石-石英。朝阳柱塞泵型号A10VSO28DFR1/31R

一般来说，有害的氡气半衰期仅为3.2天，室内氡浓度在开门窗后2～3分钟后就可降至室外水平。*简单的方法就是加强通风。刚刚装修好的房间能进行检测，如果检测结果不合格，可以用降辐射涂料或安装无铅防护板，防止氡从建材中释放。如果放射性指标过高，则必须立即更换石材。无论是天然的还是人造的大理石，铺设后都必须留心检测辐射污染情况。常见的方法就是开窗通风，如果有需要还可以安装吸收装置或安装防护板。
